Having the DNS live on a pi sounded like fun for me but it gave me stress due to power outages. There is safety in knowing you aren't adding a point of failure that only you know how to solve.
I also had issues with adding backup DNS, since a backup DNS would be queried if the pihole blocked the DNS query -- so I would have to maintain two seperate blocklists, one local and one offsite.
